...and c++17 will even have some more interesting things: new math functions that may be relevant for dsp - bessel, elliptic, etc. - so far, i had to code some...
...i want to read some dsp books again. it's been a long time. i feel like i'm getting out of practice. will probably order printed versions of these 4 soon...
hmm...within the RSLib codebase, i experimented a bit with a zdf version of my ladder filter and actually found it to respond worse to modulation than my regular udf ladder....
it's a 2-pole. the frequency responses are actually equivalent to the well trodden (i dare to say: classic) rbj cookbook biquads. if you want 4, yes, you can use in...
...i think, zdf is a bit overrated
in the case of the ladder, the unit delay in the feedback path causes the resonance frequency (and also the resonance amount) to detoriate from where it should be -...
yeah - ok, so you generate the resonance separately by some chaotic system that also gets disturbed by the input. i was just a bit confused by the phrase "oscillators...
> what is this about zeros vs poles filters are described in terms of their so called "transfer functions". these are rational functions (i.e. a quotient of two polynomials) of...
intuitively, if you have a pole near the imaginary axis (i.e. the frequency axis) - you get a boost at these frequencies near the pole, a zero at the same...
if the pole is *on* the imaginary axis, you have self-oscillation, if a zero is on the axis, you have a total notch there. if the poles/zeros are not directly...
